Unveiling the nature of HE 0107-5240
E. Caffau, M. Steffen, P. Molaro +27
The vast majority of the most iron-poor stars in the Galaxy exhibit a strong carbon enhancement, with C/H ratios only about two orders of magnitude below solar. This unusual chemic…
SOAPv4: A new step toward modeling stellar signatures in exoplanet research
E. Cristo, J. P. Faria, N. C. Santos +6
We present and describe a new version of the spot oscillation and planet code, SOAPv4. Our aim is to demonstrate its capabilities in modeling stellar activity in the context of RV…
A systematic bias in template-based RV extraction algorithms
André M. Silva, N. C. Santos, J. P. Faria +30
In this paper we identify and explore a previously unidentified, multi meter-per-second, systematic correlation between time and RVs inferred through TM and LBL methods. We evaluat…
The ESPRESSO transmission spectrum of HD189733b : Extracting the planetary sodium and lithium signatures amid stellar contamination
D. Mounzer, W. Dethier, C. Lovis +20
While transmission spectroscopy has allowed us to detect many atomic and molecular species in exoplanet atmospheres, the improvement in resolution and signal-to-noise ratio enabled…
